I think you have to get Iron ASAP. Gilgamesh will box you in quickly. Bad luck with the horses.
Does Gilgamesh have copper nearby?
Once you get Iron, I'd hit him with a sword/axe combo rush.
In the meantime, you need to expand towards Gilgamesh. I would make two cities to your west, a corn/cows/river city and a fish/hill city. This blocks off Gilgamesh, gives you a closer strike point from which to attack him, and gives you two cities that can actually produce a unit or two to contribute to the battle.
I know Gilgamesh is tough (vultures + protective archers) but being aggressive, your combat I/shock axes are superior to a vulture, even if he has combat I. This is also true for your combat I/city raider I swords. Yeah, he'll have cultural defenses, but that's why you bring the Horde:
If you don't have Iron, reroll.
